We had a brace of littermate males purchased by a doctor in penn. He brought them for Obedience and Bird training last summer, as a team they would stalk a sight bird with the lead dog crawling and the backing dog in full hi head point. They self taught this. Both these dogs are from Burdock of Coronation Breeding. Ted pm me your ph # so we can help with heeling. Graysons sisters are developing nicely retrieving to hand from land and water.
